How to remove everything from superview

Question

Rather than individually removeFromSubview for each thing I want to remove, I'd like to know if there's something which removes everything from the superview.

Answer 1

I am using category method for this

@interface UIView (Additions)
- (void)removeAllSubviews
@end

@implementation UIView (Additions)
- (void)removeAllSubviews
{
    for (UIView *subview in self.subviews)
        [subview removeFromSuperview];
}
@end

So you can call

[self.superview removeAllSubviews];

to remove everything from superview.

Answer 2

for(UIView *view in self.superview.subviews)
{
    [view removeFromSuperview];
}

Be careful with this though, it can remove Apple built-ins that you don't know are there and thereby change the way the view interacts with the user.

Answer 3

One liner

[viewYouWantToRemoveFrom.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
